MILK-SCALDER.

SPECIFICATION forming part of Letters Patent No. 464,622, dated December 8, 1891. Application iiled June 25, 1891. Serial No. 397,406.` (No model.)

To all whom t may concern:

Be it known that I, NICHOLAS W. GALES, a citizen of the United States, residing at Colo, in the county of Storey and State of Iowa, have invented certain new and useful Improvements in lWIilk-Scalders; and I do hereby declare that the following is a full, clear, and

exact description of the same, reference being had to the annexed drawings, making a part of his specification, and to the letters of reference marked thereon.

This invention relates to certain new and useful improvements in devices for and method of scaldiug milk, preferablyskimmilk, as it leaves the separators, to keep it from souring. Milk treated in accordance with my invention will keep for days.

The other objects and advantages of the invention will hereinafter appear, andthe novel features thereof will be specifically defined by the appended claims. Y

The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form apart of this specification, and in which is shown a view, partly in side elevation and partly in section, with portions broken away, of my improved apparatus.

Referring noW to the details of the drawings by letter, A'designates a recept'aclawhich may be of any desired shape and capacity, preferably of substantially the shape shown, and having at one end a discharge a, through which the milk after being scalded is allowed to pass to the desired receptacle or place. A suitable cock or valve b is provided in this discharge-pi pe, as shown. Extending into the receptacle from the other end is a perforated pipe B, preferably tapered, as shown, and extending centrally within the receptacle and for a greater part of the length thereof. This pipe B is connected with the pipe O, which is designed to be connected with the boiler or other source of steam (not shown) in any suitable manner, and between its connection with the pipe C and the receptacle the pipe B is provided with a cock or valve c, as shown. From the coupling d there extends a pipe E, provided with a cock or'valve @,-as shown, and which pipe at its lower end is turned horizontally and provided with a jet-tube D. This jet-tube is arranged within the coupling F, whichis provided with a neck fat right angles to the said tube and with which is connected the pipe G, which is designed to be connectedwith the separator (not shown) in any suitable manner or with any other receptacle from which it is desired to take the milk to be treated.

To the end of the coupling F opposite to that into which the jet-tube is introduced there is connected the pipe H, which connects with the elbow g, to which is connected the pipe I, which is connected with the receptacleA at the end nearest the entrance of the perforated pipe B, as shown. The coupling F is formed with an offset t' and the pipe II with an offset. j, in which is fitted the wooden sleeve'or lining J, which is arranged at the point where the jet-tube D delivers steam. This wooden lining prevents burning of the milk at this point and thus avoids filling up of the pipe.

In operation, the pipe O being connected 'with the source of steam, the pipe G with the milk-receptacle, and the pipe a to any desired place of deposit of the scalded milk, the

cock h is opened, the cock o closed, and the cock e opened. The flow of steam through the pipe E and jet-tube D creates -a suction which draws the milk up through the pipes G and II into the receptacle A. lVhen there is sufficient milk in the receptacle for it to pass out the discharge ot, the cock e is closed 'and the cock c opened, allowing the steam to construction is connected to the end of the receptacle A, so as to form a tight joint between it and the perforated pipe B, and thus prevent any leakage at this point.

What I claim as new isl. The combination, with the receptacle IOO ` having discharge-pipe, of the steam-pipe, the lining at the discharge end of the jet-tube, as
